I have to answer about 25 questions about one scientific text on English. I already chose one, but need I can't add URL here, and need help :(

What is the name and author of this text?

TITLE: Pet ownership, dog types and attachment to pets

in 9–10 year old children in Liverpool, UK

http://www.readcube.com/articles/10.1186/1746-6148-9-102?locale=en

That's it.

I can't decide is this text more formal or informal and what is the aimed readership?
I have to find 2 examples of definition, 2 of description, and 1 of generalization. 5 collocations. 2 markers of explanation.

Of course, I'd be happy to help you! Even without the specific URL, I can guide you through the process of answering questions about a scientific text in English. Here are some general steps you can follow:
